  • Applications

    11-Benzylheneicosane (CAS 55334-72-0) is a high-molecular-weight hydrocarbon primarily used in fragrance applications as a fixative and odor carrier, helping extend the longevity of aromatic notes in perfumery and scented consumer products. It can function as a waxy component or processing aid in cosmetics and personal care formulations, contributing to viscosity and texture. In household products and air fresheners, it acts as a non-polar carrier and fragrance modifier. In polymer and plastics formulations, it may be used as a wax-like additive to improve slip, gloss, and processing characteristics. It is occasionally evaluated as a component in coatings and inks to impart controlled volatility and film-forming behavior. Its use is subject to local regulations and formulation limits.
